The jet grouting process ” is recognized as a cement soil stabilization. With the aid of high pressure cutting jets of water or cement suspension having a nozzle exit velocity ≥100 m/sec eventually air-shrouded the soil around the borehole is eroded.The eroded soil is rearranged and mixed with the cement suspension. The soilcement mix is partly ﬂushed out to the top of the borehole through the annular space between the jet grouting rods and the borehole.
